Unbelievable.  I just started with QuickBooks and I can't even get my accounts added because of this error.  I've exhausted every known solution available.....every browser, Firefox, Chrome, Safari, Explorer, deleted cache, cookies, history, used incognito, private browsing.  I'm so disappointed with this thing.  What a colossal waste of time.   Now I'm forced to waste more time by adding this to a community.  Next step is to waste more time contacting support. I'm glad this is happening in my first month because I have no problem cancelling my subscripting and trying another provider.  

Very disappointed.
